Twilight Sagaseries of vampire-themed novels for teenagers written by American author Stephenie Meyer. The Twilight Saga includes four titles: Twilight (2005; filmed film 2008), New Moon (2006; filmed film 2009), Eclipse (2007; filmed film 2010), and Breaking Dawn (2008; film 2011). The series tells the story—fraught with danger, suspense, and searing passion—of teenager Bella Swan and her vampire boyfriend, Edward Cullen.

Twilight introduces Bella as she moves to Washington state and meets Edward, who instantly falls for her even though he is a vampire. Meyer’s second novel, New Moon (2006), in which Bella befriends a young werewolf named Jacob Black, topped the list of best-selling children’s chapter books in The New York Times within a month of its publication. In the third book, Eclipse (2007), Bella must choose between Edward and Jacob, hoping all the while that she does not inflame an age-old conflict between vampires and werewolves. In 2007 the Twilight Saga finally edged J.K. Rowling’s Harry Potter from his perennial perch atop The New York Times best-seller list for series books. Breaking Dawn, the fourth and final novel in the series, was published in 2008 and sold some 1.3 million copies in its first day on sale.

Meyer described her vampires as “very light”—sensitive, thoughtful, even beautiful figures rather than blood-guzzling predators. Some, like Edward and his family, do not drink human blood. They also do not turn into bats or sleep in coffins, and they travel abroad in daylight. This unconventional take on vampires, along with vivid characterizations and spot-on portrayals of obsessive love and other varieties of teen angst, won Meyer a fervid following among teenage girls. Notwithstanding the erotic tension of the novels, Meyer, a Mormon committed to keeping her writing consistent with her faith, eschewed sexual explicitness, a decision that made her popular with parents.
